Introduction Porous material is the important one of heat insulation materials in the aerospace industry, especially the polymer and ceramic materials are widely used because of its low conductivity[1, 2].
Therefore, the common thermal insulation materials can not satisfy the requirements of the development of high degree heat insulation.
Grasp the heat transfer properties of MR which provide a theoretical reference to the engineering application in the fields of heat insulation materials.

The successful development of high dielectric constant ceramic material enables the area of microstrip antenna to narrow several times.
Design on microstrip antenna, first make sure choose dielectric substrate materials[4].
Due to the relative permittivity and relative magnetic permeability increase so that the antenna design the size decreases, the design uses is the relative dielectric constant = 10.2, loss tangent of angle of 0.003 microwave ceramic dielectric substrate materials.
Relative dielectric constant unit width W, to determine the basic material and its thickness h should first determine the size of the unit width W.
